As used herein, the terms “smoking and/or vaporizing substance,” refers to one or more dry herbs for smoking, concentrates for smoking, and/or concentrates for vaporizing (e.g., “dab” concentrates, such as shatter, crumble, wax, budder, rosin, live resin, etc.) that are made of or include any suitable herb that can be dried and smoked, or from which smoking and/or vaporizing concentrates can be made. As non-limiting examples, “smoking and/or vaporizing substances,” may be derived from herbs, such as cannabis, tobacco, blue cornflower, blue vervain, calamus, calendula, catnip, chamomile, chrysanthemum, damiana, echinacea, eucalyptus, gotu kala, hawthorn, hibiscus, holy basil, jasmine, lavender, lemongrass, licorice root, linden, marshallow leaf, mugwort, mullein, nettle, passionflower, peppermint, raspberry leaf, rose, sage, skullcap, saint john's wort, uva ursi, wild dagga, wormwood, violet, yarrow, yerba santa, combinations of two or more of the foregoing, etc.

FIGS. 1-3 show an adjustable device 100 in an assembled state (FIG. 1 ), in a disassembled state (FIG. 2 ), and a cross-sectional view of the adjustable device 100 in a disassembled state (FIG. 3 ), in accordance with embodiments of this disclosure. The adjustable device 100 may be utilized in the context of vaporizing and/or smoking, although the use of the adjustable device 100 is in no way limited to the vaporizing and/or smoking context. In the vaporizing and/or smoking context, the adjustable device 100 may function as what is colloquially referred to as a “downstem.” A smoking and/or vaporizing substance may be placed within a vaporizing and/or smoking device (e.g., a pipe, such as a “bong,” etc.), and then the smoking and/or vaporizing substance may be heated to produce vapor and/or smoke. The adjustable device 100 may be utilized to generate a suction force to draw air, smoke, and/or vapor through the vaporizing and/or smoking device, and optionally a liquid (e.g., water), before being inhaled by a user (e.g., a human). The liquid, such as water, may help to cool and/or at least partially filter particulates from the air, smoke, and/or vapor. The adjustable device 100 may be configured to connect to (e.g., be inserted into, etc.) the vaporizing and/or smoking device in a desired manner. For example, the adjustable device 100 may be positioned such that an end portion of the adjustable device 100 is at least partially submerged within the liquid in the smoking and/or vaporizing device. The size of vaporizing and/or smoking devices may vary, so the adjustable device 100 can be adjusted as desired based on the size of the device(s) in which the adjustable device 100 will be used. The process is shown and described below with respect to FIG. 24 .

Referring collectively to FIGS. 1-3 , the adjustable device 100 generally includes a first section 101 that includes an adapter 102, and optionally, a stem 104 configured to connect to the adapter 102. The adjustable device 100 may additionally include a diffuser 106 configured to connect to the first section 101 (e.g., the adapter 102 and, optionally, the stem 104). As shown in FIG. 1 , the adjustable device 100, in the assembled state, includes the first section 101 removably connected to a diffuser 106. In some embodiments, the first section 101 includes the adapter 102 removably connected to the stem 104, and the stem is removably connected to the diffuser 106 such that the stem 104 is interposed between the adapter 102 and the diffuser 106. In additional embodiments, the first section 101 includes only the adapter 102 removably connected to the diffuser 106, and the stem 104 may be entirely omitted from the adjustable device 100. The adjustable device 100 may include a variety of configurations (FIGS. 4-23 ). Thus, in some embodiments, the adjustable device 100 includes the adapter 102 and the diffuser 106.

In the assembled state shown in FIG. 1 , the adjustable device 100, may exhibit any desired shape(s) and/or size(s). For example, as shown in FIG. 1 , the adjustable device 100, in the assembled state, may exhibit a generally elongated tubular shape.

The adjustable device 100 may define a central opening 108 that may extend continuously through each portion of the adjustable device 100 from a first end 110 of the adjustable device 100 to a second end 112 opposite the first end 110. Thus, the central opening 108 may extend substantially an entire length (e.g., a distance from the first end 110 to the second end 112) of the assembled adjustable device 100.

The adjustable device 100 may be adjustable in length (e.g., the distance from the first end 110 to the second end 112), and also in width (e.g., diameter) of the adapter 102. For example, as shown in FIGS. 1-3 , the adapter 102 may include a first portion 114 and, optionally, a second portion 116 configured to removably connect to the first portion 114. In addition, the stem 104 may include a first portion 118, a second portion 120, a third portion 122, and/or a fourth portion 124 that may each be configured to removably connect to one another. Thus, the vertical dimension (e.g., dimension in the Z-direction) of the adjustable device 100 may vary, and the lateral dimension(s) (e.g., dimensions in the X-direction and/or Y-direction) of at least a portion (e.g., the adapter 102) of the adjustable device 100 may vary depending on a particular configuration. Portions of the adjustable device 100, including the portions 114, 116 of the adapter 102, and/or the portions 118, 120, 122, 124 of the stem 104 may be mixed and matched as desired to form a variety of configurations of the adjustable device 100. In some embodiments, each of the adapter 102, the stem 104, and the diffuser 106 include common connection features (e.g., same shape, size, and/or type) such that the diffuser 106 is configured to connect to the stem 104, or the adapter 102, and the stem 104 is configured to connect to the adapter 102. Various configurations of the adjustable device 100 are shown and described below with respect to FIGS. 4-23 .

Continuing with reference to FIGS. 1-3 , the adapter 102 may exhibit any desired shape and/or size. In some embodiments, the adapter 102 may be configured to interface with a portion of another device, such as a “bowl” section and/or the bowl of a smoking and/or vaporizing device (see FIG. 24 ). For example, the lateral dimension(s) (e.g., in the X-direction and/or Y-direction) of the adapter 102 may be corresponding to that of the smoking and/or vaporizing device in which the adapter 102 and remainder of the adjustable device 100 will be used. Because smoking and/or vaporizing devices may exhibit different shapes and sizes, and the shape and size (e.g., lateral dimensions, such as a diameter) of the bowl section and/or bowl may also vary, the size of the adapter 102 may also vary (e.g., by adding or subtracting the second portion 116) to complement the size and shape of the bowl. Accordingly the adapter 102 may transition from a first diameter to a second diameter by adding and/or subtracting the second portion 116 from the first portion 114 of the adapter.

In some embodiments, the adapter 102 includes only the first portion 114. In additional embodiments, the adapter 102 includes both the first portion 114 and the second portion 116 removably connected to the first portion 114. To facilitate a removable connection between the first portion 114 and the second portion 116 of the adapter 102, the second portion 116 may include a first connection feature 125. The first connection feature 125 of the second portion 116 may be configured to engage a first connection feature 127 of the first portion 114. For example, the first connection feature 127 may correspond to (e.g., be complementary to) the first connection feature 125.

In some embodiments, the first connection feature 125 of the second portion 116 may include lip 126 and an exterior recessed section 128 adjacent the lip 126 (e.g., in the Z-direction). In addition, the first connection feature 127 of the first portion 114 may include a ridge 132 configured to rest against a surface of the second portion 116, and a corresponding interior recessed section 134 configured to receive the first connection feature 125 (e.g., the lip 126) of the second portion 116 of the adapter 102.

In additional embodiments, the first connection feature 127 of the first portion 114 may include threads, pins, openings, etc. and the first connection feature 125 of the second portion 116 may include corresponding (e.g., complementary) threads, openings, pins, etc. to removably connect (e.g., secure) the first portion 114 to the second portion 116.

The size of the first connection feature 125 (e.g., the lip 126) of the second portion 116, and the size of the first connection feature 127 (e.g., interior recessed section 134) of the first portion 114 may be a different size (e.g., larger or smaller) than other connection features between portions of the adjustable device 100. which may inhibit (e.g., prevent) the second portion 116 of the adapter 102 from inadvertently being connected to a portion of the stem 104 or the diffuser 106.

The first portion 114 of the adapter 102 may exhibit any desired tubular shape. For example, the first portion 114 of the adapter 102 may exhibit a chisel shape, a frustoconical shape, a conical shape, a dome shape, an elliptical cylinder shape, a circular cylinder shape, a pillar shape, a truncated version of one of the foregoing shapes, or a combination of two or more of the foregoing shapes. As shown in FIGS. 1-3 , the first portion 114 may exhibit a tapered shape such that a first end of the first portion 114 is larger (e.g., laterally) than a second end of the first portion 114, which may facilitate a connection to the second portion 116 of the adapter 102 and/or another device, such as, for example, a smoking and/or vaporizing device.

The first portion 114 of the adapter 102 may exhibit any desired size, such as any desired lateral dimension(s) (e.g., in the X-direction and/or Y-direction), and/or any desired longitudinal dimension(s) (e.g., in the Z-direction). For example, the first portion 114 of the adapter 102 may exhibit lateral dimension(s) (e.g., a diameter) within a range of from about 10 millimeters (mm) to about 20 mm, such as from about 12 mm to about 18 mm, from about 13 mm to about 16 mm, such as about 12 mm, about 14 mm, or about 16 mm. In addition, the first portion 114 of the adapter 102 may exhibit a maximum longitudinal dimension of from about 10 mm to about 50 mm, such as from about 15 mm to about 45 mm, from about 20 mm to about 40 mm, from about 25 mm to about 35 mm, (e.g., about 28 mm, about 30 mm, or about 32 mm).

The second portion 116 of the adapter 102 may exhibit any desired tubular shape. For example, the second portion 116 of the adapter 102 may exhibit a chisel shape, a frustoconical shape, a conical shape, a dome shape, an elliptical cylinder shape, a circular cylinder shape, a pillar shape, a truncated version of one of the foregoing shapes, or a combination of two or more of the foregoing shapes. As shown in FIGS. 1-3 , the second portion 116 may exhibit a tapered shape such that a first end of the second portion 116 is wider than a second end of the second portion 116, which may facilitate a connection to another device, such as, for example, a smoking and/or vaporizing device. For example, the second end (e.g., narrow end) of the second portion 116 may be substantially the same size (e.g., laterally) as the ridge 132 of the first portion 114. In some embodiments, the second portion 116 of the adapter 102 exhibits substantially the same shape as the first portion 114. In additional embodiments, the second portion 116 of the adapter 102 exhibits a different shape than the first portion 114.

The second portion 116 of the adapter 102 may exhibit any desired size, such as any desired lateral dimension(s) (e.g., in the X-direction and/or Y-direction), and/or any desired longitudinal dimension(s) (e.g., in the Z-direction). For example, the second portion 116 of the adapter 102 may exhibit lateral dimension(s) (e.g., a diameter) within a range of from about 10 mm to about 30 mm, such as from about 12 mm to about 28 mm, from about 14 mm, to about 26 mm, from about 16 mm to about 24 mm, from about 18 mm to about 22 mm (e.g., about 19 mm or about 20 mm). In addition, the second portion 116 of the adapter 102 may exhibit a maximum longitudinal dimension of from about 10 mm to about 50 mm, such as from about 15 mm to about 45 mm, from about 20 mm to about 40 mm, from about 25 mm to about 35 mm, (e.g., about 28 mm, about 30 mm, or about 32 mm). In some embodiments, the second portion 116 of the adapter 102 exhibits substantially the same longitudinal dimension (e.g., length) as the first portion 114. In additional embodiments, the second portion 116 of the adapter 102 exhibits a different longitudinal dimension (e.g., length) than the first portion 114.

The adapter 102 may be configured to connect to the stem 104 and/or the diffuser 106. For example, the first portion 114 of the adapter 102 may be configured to connect to any of the portions 118, 120, 122, 124 of the stem 104 and/or the diffuser 106. To facilitate a removable connection between the first portion 114 of the adapter 102 and the stem 104 (e.g., the first portion 118 of the stem 104), the first portion 114 of the adapter 102 may include a second connection feature 135 configured to connect to a first connection feature 137 of the first portion 118 of the stem 104. For example, the first connection feature 137 of the first portion 118 of the stem 104 may correspond to (e.g., be complementary to) the second connection feature 135 of the first portion 114 of the adapter 102.

In some embodiments, the second connection feature 135 of the first portion 114 of the adapter 102 may include lip 136 and an exterior recessed section 138 adjacent the lip 136 (e.g., in the Z-direction). The first connection feature 137 of the first portion 118 of the stem 104 may include a corresponding interior recessed section 140 (e.g., complementary interior recessed section) configured to receive the second connection feature 135 (e.g., the lip 136) of the first portion 114 of the adapter 102.

In additional embodiments, the second connection feature 135 of the first portion 114 of the adapter 102 may include threads, pins, openings, etc. and the first connection feature 137 of the first portion 118 of the stem 104 may include corresponding (e.g., complementary) threads, openings, pins, etc. to removably connect (e.g., secure) the first portion 114 of the adapter to the first portion 118 of the stem 104.

The size of the second connection feature 135 of (e.g., the lip 136, threads, openings, pins, etc.) of the first portion 114 of the adapter 102, and the corresponding connection feature 137 (e.g., the interior recessed section 140, threads, pins, openings, etc.) of the first portion 118 of the stem 104 may be substantially the same size as other connection features between the first portion 114 of the adapter 102, portions 118, 120, 122, 124 of the stem 104, and/or the diffuser 106 of the adjustable device 100. Common connection features (e.g., same size, shape, and/or type etc.) between portions 114, 118, 120, 122, 124, and/or 106 of the adjustable device 100 may facilitate portions 114, 118, 120, 122, 124, and/or 106 of the adjustable device 100 being mixed and matched with one another to change the longitudinal dimension (e.g., in the Z-direction) of the adjustable device 100.

The first portion 118 of the stem 104 may exhibit any desired tubular shape. For example, the first portion 118 of the stem 104 may exhibit a chisel shape, a frustoconical shape, a conical shape, a dome shape, an elliptical cylinder shape, a circular cylinder shape, a pillar shape, a truncated version of one of the foregoing shapes, or a combination of two or more of the foregoing shapes. As shown in FIGS. 1-3 , the first portion 118 may exhibit a cylindrical shape such that a first end of the first portion 118 is substantially the same size as a second end of the first portion 118, which may facilitate the first portion 118 being inserted into another device, such as, for example, a smoking and/or vaporizing device.

The first portion 118 of the stem 104 may exhibit any desired size, such as any desired lateral dimension(s) (e.g., in the X-direction and/or Y-direction), and/or any desired longitudinal dimension(s) (e.g., in the Z-direction). For example, the first portion 118 of the stem 104 may exhibit lateral dimension(s) (e.g., a diameter) within a range of from about 10 mm to about 20 mm, such as from about 12 mm to about 18 mm, from about 13 mm to about 16 mm, such as about 12 mm, about 14 mm, or about 16 mm. In addition, the first portion 118 of the stem 104 may exhibit a maximum longitudinal dimension within a range of from about 10 mm to about 100 mm, such as from about 25 mm to about 100 mm, from about 40 mm to about 90 mm, from about 50 mm to about 90 mm, such as about 70 mm or about 80 mm (e.g., about 76 mm or about 3 inches).

The first portion 118 of the stem 104 may be configured to connect to the first portion 114 of the adapter, another portion 120, 122, 124 of the stem 104, and/or the diffuser 106. To facilitate a removable connection between the first portion 118 of the stem 104 and another portion of the stem 104 (e.g., the second portion 120 of the stem 104), the first portion 118 may include a second connection feature 141 configured to connect to a first connection feature 143 of the second portion 120 of the stem 104. For example, the first connection feature 143 of the second portion 120 of the stem 104 may correspond to (e.g., be complementary to) the second connection feature 141 of the first portion 118 of the stem 104.

In some embodiments, the second connection feature 141 may include lip 142 and an exterior recessed section 144 adjacent the lip 142 (e.g., in the Z-direction). The first connection feature 143 of the second portion 120 of the stem 104 may include a corresponding interior recessed section 146 (e.g., complementary interior recessed section) configured to receive the second connection feature 141 (e.g., lip 142) of the first portion 118 of the stem 104.

In additional embodiments, the second connection feature 141 of the first portion 118 of the stem 104 may include threads, pins, openings, etc. and the first connection feature 143 of the second portion 120 of the stem 104 may include corresponding (e.g., complementary) threads, openings, pins, etc. to removably connect (e.g., secure) the first portion 118 to the second portion 120.

The size of the second connection feature 141 (e.g., the lip 142) of the first portion 118 of the stem 104, and the first connection feature 143 (e.g., the interior recessed section 146) of the second portion 120 of the stem 104 may be substantially the same size as other lips and recessed sections between the first portion 114 of the adapter, portions 120, 122, 124 of the stem 104, and/or the diffuser 106 of the adjustable device 100. Common connection features (e.g., same size, shape, and/or type etc.) between portions 114, 118, 120, 122, 124, and/or 106 may facilitate portions 114, 118, 120, 122, 124, and/or 106 of the adjustable device 100 being mixed and matched with one another to change the longitudinal dimension (e.g., in the Z-direction) of the adjustable device 100.

The second portion 120 of the stem 104 may exhibit any desired tubular shape. For example, the second portion 120 of the stem 104 may exhibit a chisel shape, a frustoconical shape, a conical shape, a dome shape, an elliptical cylinder shape, a circular cylinder shape, a pillar shape, a truncated version of one of the foregoing shapes, or a combination of two or more of the foregoing shapes. As shown in FIGS. 1-3 , the second portion 120 may exhibit a cylindrical shape such that a first end of the second portion 120 is substantially the same size as a second end of the second portion 120, which may facilitate the second portion 120 being inserted into another device, such as, for example, a smoking and/or vaporizing device.

The second portion 120 of the stem 104 may exhibit any desired size, such as any desired lateral dimension(s) (e.g., in the X-direction and/or Y-direction), and/or any desired longitudinal dimension(s) (e.g., in the Z-direction). For example, the second portion 120 of the stem 104 may exhibit lateral dimension(s) (e.g., a diameter) within a range of from about 10 mm to about 20 mm, such as from about 12 mm to about 18 mm, from about 13 mm to about 16 mm, such as about 12 mm, about 14 mm, or about 16 mm. In addition, the second portion 120 of the stem 104 may exhibit a maximum longitudinal dimension within a range of from about 10 mm to about 100 mm, such as from about 20 mm to about 90 mm, from about 30 mm to about 80 mm, from about 40 mm to about 70 mm, such as about 50 mm or about 60 mm (e.g., about 57 mm or about 2.25 inches).

For example, the first connection feature 161 of the diffuser 106 may correspond to (e.g., be complementary to) the second connection feature 159 of the fourth portion 124 of the stem 104.

In some embodiments, the second connection feature 159 may include a lip 160 and an exterior recessed section 162 adjacent the lip 160 (e.g., in the Z-direction). The first connection feature 161 of the diffuser 106 may include a corresponding interior recessed section 164 (e.g., a complementary interior recessed section) configured to receive the second connection feature 159 (e.g., the lip 154) of the fourth portion 124 of the stem 104.

In additional embodiments, the second connection feature 159 of the fourth portion 124 of the stem 104 may include threads, pins, openings, etc. and the first connection feature 161 of the diffuser 106 may include corresponding (e.g., complementary) threads, openings, pins, etc. to removably connect (e.g., secure) the fourth portion 124 to the diffuser 106.

The size of the second connection feature 159 (e.g., the lip 160) of the fourth portion 124 of the stem 104, and the first connection feature 161 (e.g., the interior recessed section 164) of the diffuser 106 may be substantially the same size as other connection features between the first portion 114 of the adapter and/or the portions 118, 120, 122, and/or 124 of the stem 104 of the adjustable device 100. Common connection features (e.g., same size, shape, and/or type etc.) between portions 114, 118, 120, 122, 124, and/or 106 may facilitate portions 114, 118, 120, 122, 124, and/or 106 of the adjustable device 100 being mixed and matched with one another to change the longitudinal dimension (e.g., in the Z-direction) of the adjustable device 100.

The diffuser 106 may be utilized to disperse air, vapor, and/or smoke to facilitate thermal transfer of heat and/or improve cooling of the air, vapor, and/or smoke traveling through the adjustable device 100 during use (e.g., in a vaporizing and/or smoking device, such as a pipe). Accordingly, the diffuser 106 is generally located at one end (e.g., the first end 110) of the adjustable device 100 in the assembled state, and the adapter 102 is generally located at another end (e.g., the second end 112), opposite the end with the diffuser 106. To facilitate dispersing air, vapor, and/or smoke traveling through the adjustable device 100 (e.g., from the second end 112 to the first end 110), the diffuser 106 defines an end opening 166 and additional openings 168 oriented laterally around and longitudinally along the diffuser 106. For example, sidewalls of the diffuser 106 may define the end opening 166 additional openings 168 that may be used to disperse air, vapor, and/or smoke through the diffuser 106. The end opening 166 may be smaller than a remaining portion of a central cavity of the diffuser 106 to promote flow outside of both the end opening 166 and the additional openings 168. In some embodiments, the size of the end opening 166 may be substantially the same size as the additional openings 168. In additional embodiments, the size of the end opening 166 may be different than the size of the additional openings 168.

In some embodiments, liquid resin (e.g., including a photoreactive material) may be preheated to a desired viscosity, and the liquid resin may be deposited where required to form the first layer. Support structures may be printed simultaneously with the part for stability during printing. The deposited material may then exposed to UV light, which cures and solidifies the layer of material. Once the first layer has solidified, the build platform may be lowered by one layer heights and the process is repeated until the part is finished.

It is noted that connection features disclosed herein may be swapped. More specifically, rather than a first piece have a female connector that connects to a second piece having a male connection, the first piece may have a male connector that connects to the second piece having a female connector. Further, it is noted that although openings 168 are illustrated as holes, the disclosure is not so limited and openings 168 may include slits or other suitable venting elements.

The same relationship exists between FIGS. 15 and 5 , FIGS. 16 and 6 , FIGS. 17 and 7 , FIGS. 18 and 8 , FIGS. 19 and 9 , FIGS. 20 and 10 , FIGS. 21 and 11 , FIGS. 22 and 12 , and FIGS. 23 and 13 .

FIG. 24 is a side view of a system 200 that includes the adjustable device 100 in operation, in accordance with embodiments of this disclosure. The system 200 generally includes the adjustable device 100 and a pipe 202. The pipe 202 includes a first end 204 (e.g., an upstream end), a second end 206 (e.g., a downstream end) opposite the first end 204, and a base 208 (e.g., a chamber) between the first end 204 and the second end 206. The base 208 may include an interior surface 209. During use, air, vapor, and/or smoke generally flows through the pipe 202 from the first end 204 through the base 208 and exits from the second end 206 due to a suction force applied at the second end 206. The base 208 may be configured to store a liquid, such as water, that may be utilized to cool and/or at least partially filter the air, vapor, and/or smoke that travels through the pipe 202.

The first end 204 of the pipe 202 may include an annular portion 210 that includes a central longitudinal axis 212. The annular portion 210 may be configured to receive at least a portion of the adjustable device 100. Accordingly, the size (e.g., dimensions in the X-direction and/or Y-direction) of the annular portion 210 of the pipe 202 may be substantially the same size as the lateral dimensions (e.g., dimensions in the X-direction and/or Y-direction) of the adjustable device 100. Accordingly, the adapter 102 (e.g., the first portion 114 or the second portion 116, if present) may be configured to connect (e.g., fixedly connect) to an end 214 of the annular portion 210 to secure the adjustable device 100 to the pipe 202. As shown in FIG. 24 , the stem 104 of the adjustable device 100 is positioned within the annular portion 210 of the pipe 202, and the second portion 116 of the adapter 102 is connected to the end 214 of the annular portion 210. To optimize the cooling and/or filtration of the air, smoke, and/or vapor during use, the longitudinal dimension (e.g., the length) of the adjustable device 100 may be selected based on the size of the pipe 202 such that the diffuser 106 at the end of the adjustable device 100 is a distance D (defining a distance measured from the interior surface 209 of the base 208 of the pipe 202 to the distalmost portion of the diffuser 106 relative to the interior surface 209). For example, the distance D may be within a range of from about 1 mm to about 300 mm, such as from about 3 mm to about 100, from about 5 mm to about 50 mm. As non-limiting examples, the distance D may be about 5 mm, about 10 mm, about 15 mm, about 20 mm, about 30 mm, about 40 mm, about 50 mm, about 60 mm, about 70 mm, about 80 mm, about 90 mm, or about 100 mm. In addition, the distance D may be less than or equal to a liquid level (e.g., water level) of fluid within the base 208 of the pipe 202 such that the diffuser 106 is at least partially (e.g., entirely) submerged in liquid within the base 208 of the pipe 202.

Accordingly, before using the pipe 202, the various portions of the adjustable device 100 may be mixed and matched to achieve a desired length of the adjustable device 100 such that the diffuser 106 will be submerged in liquid within the pipe 202 during use.

A bowl 216 may then be connected (e.g., secured) to the end of the second portion 116 of the adapter 102 within the central opening 108 of the adjustable device 100. A smoking and/or vaporizing substance may be inserted into the bowl 216, and the smoking and/or vaporizing substance may be ignited and/or vaporized and mixed with ambient air. A suction force is then applied at the second end 206 of the pipe 202 (e.g., a by a user inhaling), and the resulting air, smoke, and/or vapor travels through the central opening 108 of the adjustable device 100, through the end opening 166 and/or the additional openings 168 of the diffuser 106, through the liquid within the base 208 of the pipe 202, and to the second end 206 of the pipe.
